1. Introduction Dear Customer, Thank you for purchasing this product. This product complies with the statutory national and European requirements. To maintain this status and to ensure safe operation, you as the user must observe these operating instructions! These operating instructions are part of this product. They contain important notes on commissioning and handling. Also consider this if you pass on the product to any third party.
Page 5: Intended Use
3. Intended Use The 3D printer produces single-coloured 3D-objects from suitable printing files. For this, suitable raw material (filament) is melted in the print head and attached in the required position for the object. The voltage supply is provided solely via the enclosed external mains unit. It is intended for indoor operation only. Do not use it outdoors. Contact with moisture, e.g. in bathrooms, must be avoided under all circum- stances.
Page 6: Safety Notes
4. Safety Notes Read the operating instructions attentively and particularly observe the safety notes. If the safety notes and the information in these operating instructions regarding proper handling are not observed, we assume no liability for any resulting injury/ property damage. In such cases, the warranty/guarantee will also lapse. a) General Information • For safety reasons, any unauthorized conversions and/or modifications to the product deviating from these operating instructions are not permitted. Components may be damaged and thus impair the function or safety of the device. • All persons who operate this product, mount, install, assemble it, put it into operation or service it must be trained and qualified accordingly and must observe these operating instructions. • The 3D printer is not suitable for persons with physical, sensor or metal limitations or for inexperienced or uninformed persons. • This product is not a toy, not to be used by children and not suitable for children. Children do not understand how dangerous electri- cal devices can be.
Page 7: C) Set-Up, Site Of Operation
c) Set-Up, Site of Operation • Set up the 3D printer only on a stable, horizontal, sufficiently sized surface. • Choose the site of operation so that children cannot reach the product. • When setting up the 3D printer, observe that the mains plug of the mains unit must be easy to reach so that the device can be separated from the mains voltage quickly and easily in case of malfunction. • The devices must not be exposed to any extreme temperatures, strong vibrations, high moisture, such as rain or steam or strong mechanical strain. • Never place containers containing liquids, e.g. glasses, vases, etc. on the device or in its vicinity and do not pour any liquids out over the device. Liquids may get into the housing and impair electrical safety. This also poses great danger of fire or potentially fatal electric shock! If this is the case, first power down the respective mains socket on all poles (e.g. switch off circuit breaker and FI switch) and then pull the mains cable of the mains unit from the socket. Disconnect all lines from the device. Do not operate any part of the product anymore afterwards, but take it to a specialist workshop.

Working Principle of the 3D Printer For 3D print, first a file is needed that contains the three-dimensional data of the object to be printed (a common format of such a file is, e.g., a .stl-file). This file can be produced with the corresponding software or with a 3D-scanner. There are also many printing files online that can be down- loaded to print an object as quickly as possible. The actual printer software has the task to render the above three-dimensional file into a file that the printer can print. This is a file in which the individual print layers, the print temperatures for the printing head and heating bed (preassembled device only), etc. are specified. The file has the extension ".gcode".

8. Software and Firmware Installation a) Download and Unpacking of the Software/Firmware Package The software, firmware, tools and printing examples needed for the printer are available online as a download package. This is regularly updated. Therefore, check occasionally whether a new version may be available. • Open the web browser and navigate either to the product page of the printer in our shop www.conrad.com or to our download page (see chapter "3. Intended Use" - Current operating instructions). • Download the package "BUNDEL_Vx_x_x_RENKFORCE_RF500" here (x_x_x designates the package version). • Unpack the downloaded ZIP file on your hard disc. Note that the archive has a very deep path due to the firmware and Arduino software contained. Therefore, we recommend directly unpacking the package into a folder on, e.g., C:\ or D:\. • Find a brief explanation on the folders contained below. "Arduino"...
Page 12: C) Installation Of The Repeater Host Software
c) Installation of the Repeater Host Software • Install the file "setupRepetierHostRenkforce_x_x_x.exe" from the directory "Repetier-Host" from the download package (x_x_x desig- nates the software version here). Installation of the custom version of the Repetier-Host requires administrator rights, since the necessary configuration files and printer settings will not be installed otherwise.

10. Assembly of the Mechanical Parts This chapter ("10. Assembly of the Mechanical Parts") generally is only relevant for purchasers of the maker construction kit / con- struction kit. Owners of the preassembled device can skip this chapter. However, the chapter is helpful when there is an error or smaller repairs are necessary. a) General Information Take enough time for the assembly. Hurrying often leads to mistakes that may damage components or ruin the time benefit by elaborate rework. The workplace should be sufficiently large and clean so that the different components and assemblies can be put down and installed easily. Always observe the images during assembly. Here, the assembly locations and correct alignment of the components are shown. All mechanical components of the construction kit are produced extremely precisely. Never apply any force during assem- bly. All parts can be assembled without any great application of force. If this is not the case, rethink the assembly step and reread the corresponding description in these instructions.

11. Mounting of the Electrical Components This chapter ("11. Mounting of the electric components") generally is only relevant for purchasers of the maker construction kit / construction kit. Owners of the preassembled device can skip this chapter. However, the chapter is helpful when there is an error or smaller repairs are necessary. The components on the PCBs can be damaged by electrostatic discharge. Therefore, touch, e.g. an earthed radiator before taking any PCBs into your hand. In subchapter c), you will find a wiring plan for the main PCB in which the required line connections are marked. The table also describes the assignment and properties of the individual cables. Before you take the printer into operation, check all cables again for accuracy and proper connection on the main PCB. If you want to mount the metal housing, please observe the additional accessory instructions before installing the main board on the board holder! a) Installation of the Electrical Components Assembly of the extruder 1x heating block Cut about 2 to 3 cm thread sealing tape off of the roll and wind it 1x nozzle 0.4 mm around the thread of the nozzle.

Page 88: C) Setup And Transport
c) Setup and Transport When setting up the 3D printer, observe that the mains unit and the mains cable must be easy to reach so that the device can be switched off quickly and easily or be disconnected from the voltage supply in case of malfunction. Ensure proper ventilation when setting up the device. Do not put the device down on soft support such as a carpet or bed, etc. the air circulation also must not be impaired by other objects. This prevents heat dissipation from the product and may lead to overheating (danger of fire). When setting up the device, make sure that it has a stable footing and place it on a stable underground. Persons may be injured if the 3D printer drops. When setting up the device, make sure that the connection cables are neither pinched nor damaged by sharp edges. Always place the cables so that no one can trip over them or be caught in them. There is a danger of injury. Never place the device on any valuable or sensitive furniture surfaces without sufficient protection. • Put up the 3D printer on a level, stable and non-vibration-sensitive surface. • If you want to transport the 3D-printer, disconnect the mains unit from the main PCB, by disconnecting the green plug (first disconnect the mains unit from the mains). Also remove the printing plate support (only in the construction kit). Only use suitable packaging for dispatch! Particularly observe that all moving parts are secured, e.g. with cable ties! Pack the printing plate support separately in bubble wrap (construction kit only).
Page 89: E) Adjustment Of The Motor Driver
e) Adjustment of the Motor Driver Before first use of the printer, the 4 motor drivers must be reconciled. This is done generally at first by comparing the potentiometer on your controller to the respective screen. Finally, the fine settings are made with a digital multimeter. This should be able to meas- ure 300 mV and 500 mV as precisely as possible. This subchapter is only relevant for purchasers of the maker construction kit, since the motor drivers in the preassembled device have already been reconciled in production. Owners of the preassembled device can therefore skip this chapter. It is, however also possible that the motor drivers need to be adjusted later.

Page 95: Calibration
15. Calibration a) General Notes on Calibration Attention! Never touch the hot extruder or the hot heat bed (preassembled device only)! There is a danger of burns! When heating, there may be slight development of smoke or steam. This is normal. Please ensure the corresponding ven- tilation. While calibration is underway, no filament must be inserted in the extruder. If there already is some filament in the extruder, it must be completely removed before calibration. For this, observe chapter "16. c) Removing and Changing the Filament" or method 3 in chapter "21. b) Cleaning". Also ensure that the extruder nozzle is clean on the outside. If it is contaminated, clean it as described in chapter "21. b) Cleaning". The extruder or the nozzle must be cleaned so that no filament escapes anymore when they are heated to printing tempera- ture. The following description shows calibration universally for the maker construction kit and the preassembled device. Subchapters "15.

Page 107: First Print Of An Example Object From The Sd Card
17. First Print of an Example Object from the SD Card When heating, there may be slight development of smoke or steam. This is normal. Please ensure the corresponding ven- tilation. If you are using PLA filament for printing and using the maker construction kit, stick the enclosed adhesive film on the printing plate for better adhesion of the printed object. Use the enclosed glue stick for the preassembled device. Alternatively, you can use a slightly structure masking tape or special glue adhesive masking tape (Conrad order no. 1093104) that has been developed specifically for this purpose. The printing files can be found in the download package in the folder GCODE-PLA. Before starting, download the current download bundle. The corresponding download can be found on the product page of our website or in the download area. In our example, the object "20_20_20Q.gcode" from the download bundle is printed. Please note! The preassembled file from the download bundle is sliced without heating. If you are using the preassembled device or the construction kit with heating, slice the file anew (instructions starting in chapter "19. e) Placement of a Printing Object in the Software"). You may need to activate heating in the slicer settings first (chapter "19. h) More Detailed Description of the Slicer Func- tions"). Alternatively, you can use the adhesive film or adhesive tape to increase adhesion.
Page 108 The display switches back automatically to the main menu. The extruder is heated up. Then move the axes to their home positions. Once the extruder has reached its operating temperature, printing When the fan starts to run, the current speed is displayed under the starts. The display shows the positions of the individual axes (7). The fan symbol in % (6).
Page 109 It is possible that filament chips collect over time at the filament feed knurl. They should be removed under all circum- stances (if possible) at once, e.g. by blowing off. Check and clean the filament feed knurl regularly! Otherwise, it is possible that the chips will adhere to the knurl and that no filament can be conveyed anymore because of this (the knurl slips through then). The fan at the extruder runs by default from 4th layer for PLA and ABS, provided that the slicer settings have not been changed. If the fan does not run properly, check if it may be attached unevenly.
Page 110: General Notes On 3D Printing
18. General Notes on 3D Printing The print quality of 3D printers depends on a great many factors. It is not always possible to achieve a satisfactory print result at the first attempt. Extruder temperature The best extruder temperature depends on the filament material and the printer layer thickness. The manufacturer information for the printing temperature can vary very strongly here. Perform the first test prints at a temperature in the middle range of the manufacturer's information. To optimise the print quality, print the same object with the same printing layer thickness and different extruder temperatures in 5 °C steps and then compare the results. This way you can approach the best extruder temperature for different filaments and printing layer thicknesses most easily. If the extruder temperature is set too hot, the material cannot cool off fast enough and will melt the layer below again. If the extruder temperature is too low, the filament will not become liquid enough and the filament flow is not homogeneous. The individual fila- ment layers also cannot combine sufficiently.

19. Software "Repetier-Host" a) General Notes on Software It is unfortunately not possible to explain the complete function of the enclosed software in the scope of this instruction. For this, we refer to the integrated online help function and the information on www.repetier.com. The basic operation and the path to the first printout are, however, described below to that you can get a result quickly and easily.
Page 112: C) Connection Of The Connected Printer
c) Connection of the Connected Printer Start the programme Repetier-Host and click on "Printer Settings" at the upper right in the window. (1) Select the printer "RF500_3D" in the menu above. (2) Set the port and check the baud rate. If you have selected the right printer in (1), the baudrate (2) is already correctly pre-set to "115200". The port number (2) is system-dependent. Usually, the setting "Auto" should work with the current version of the software (as of 1.6.2). If this does not work properly for you, you can check the port in the device manager of the control panel, under connections (COM and LPT).
Page 113 Click "Connect" in the upper left of the main screen of the software. After a few seconds, the symbol appears in green and the label turns to "Disconnect". The printer has successfully been connected to the software and only some manual settings can be tested.
Page 114: D) Manual Operation Via The Software
d) Manual Operation via the Software Click the tab "Manual Control" (1) on the main screen of the software. Before trying out manual printer control, the settings for the limit switches for the Z and Y axes must have been performed. In the preassembled device, the basic settings have already been performed at production but should be inspected again for reasons of safety. If this is not observed, there may be damage to the 3D printer (loss of warranty/guarantee).

Page 115: E) Placement Of A Printing Object In The Software
e) Placement of a Printing Object in the Software Click the "+" symbol on the main screen of the software in the object placement tab. Select the desired file and click "OK". Alternatively, you can also simply pull the file into the software. The 3D object "drops" onto the printing plate in the main window. The following file types can be opened with this software: *.stl (STL-files) *.obj (OBJ-files) *.3ds (3D-Studio-files) In the folder "STL" in the download package, you will find a few examples for the first printing attempts. However, there are many places online where you can download 3D files (e.g. www.thingiverse.com). Alternatively, you can, of course, also use a 3D programme to make your own.
Page 116 Short description of the most important buttons in the "Object Placement" tab: (1) Saving the object (2) Adding objects (as described above); several objects can be addend (3) Copying objects for multiple printing (in another window, the number of copies can be chosen) (4) Centring the object on the printing plate (5) Mirroring the object (6) Deleting the object from the printing plate (7) Scaling the object Use the scaling function to compensate the size retention of the printed object here as well. If it is known, e.g., that the filament material used shrinks by 2 %, set the scaling to the value 1.02 (this is an approximate reference value). After printout, you can meas- ure the object and adjust scaling again if required. (8) Turning the object (9) Showing the cross-section of the object 1 2 3...
Page 117: F) Preparation For Print
f) Preparation for Print To be able to print the object, it first needs to be sliced into individual printing layers. This process is referred to as "slicing". Slicing of the placed printing object (1) Select suitable slicer settings for your print. The settings are always marked with the following routine: Printer_Filament material_Layer thickness_Nozzle diameter Example: RF500_PLA175_200_04 = RF500_1.75 mm PLA_layer thickness 200 µm (= 0.2 mm)_nozzle diameter 0.4 mm Always use the same settings in the input fields "Print Setting", "Printer Settings" and "Extruder 1". The heating in the profiles for PLA is switched off by default. If you want to use these, you need to activate the function in the cor- responding slicer profile (see chapter "19. h) More Detailed Description of the Slicer Functions"). (2) Further settings can be made optionally here. However, this should only be done by experienced users. For functions, see the online help function of the software. (3) Click "Slice with Slic3r", to slice the 3D file. The best printing results can be achieved with the profile with the smallest layer thickness. This would be the profile "RF500_PLA175_100_ 04". Printing will take longer accordingly.
Page 118 The preassembled printing file appears in the graphics window after calculation. To the right of this, you will see a small overview for printing. This layer view serves to check for errors before printing. At the very left of the screen, there is a tool bar that serves view control. For more detailed descriptions of the functions, see the online help function of the software.
Page 119: G) Print
g) Printing The printing file produced in this manner can be printed now. There are two options for this: • Save the printing file on an SD card to print out stand-alone. For this, click "Save to file" (1). This saves the file as *.gcode and must be set at the same time when you save the file from the G-code editor (disc icon). The precise content of the G-code will be saved into the file here. • The second possibility is to send the file directly to the connected 3D printer via the USB interface of the computer and print it. • Click "Print Preview" and then the button "Print" (3), to start the printout. • While printing, the log window (4) below the image shows current information on software, slicer and printer. • You can also track progress of your print in the main window (5).
Page 120 The graphics window may be switched to display temperature curves. There, the temperatures and their course are graphically displayed in a chart. During the first centimetres of printing, the distance between the printing plate support and extruder can be carefully fine-adjusted manually with the 4 knurled screws at the bottom of the pressure plate. Turn all 4 knurls alternatingly and observe the printed line. For this setting, observe that the extruder must not touch the printing plate support since it may be damaged otherwise (loss of warranty/guarantee).
Page 121: H) More Detailed Description Of The Slicer Functions
h) More Detailed Description of the Slicer Functions Below some settings of the slicer are explained that are only to be changed by experienced users. The use of wrong set- tings can result in damage to the 3D printer or defective printouts. Beginners should first work with the basic settings that are integrated in the custom version in any case. If you make any changes to the settings, these must be saved in the configuration settings by clicking the disc icon. Save the different settings as a configuration setting. Assign unique names for the different configuration settings so that you can assign them uniquely to the different filament types, print resolutions, etc. later. For more information, read the integrated online help function. Click the software in the tab "Slicer" (1) to "Configuration" (2) in the right window. The Slicer window is opened (this may take a few seconds).
Page 122 Print Settings (1) Layer height (resolution of the printed object) (2) Layer height of the first layer (influences the adjustment and adhesion on the printing plate; set the first layer a little thicker than the follow- ing layers) (3) Number of the outer wall layers (4) Activate for hollow bodies (e.g. vases) (5) Filled layer number top/bottom (1) Object filling (0-100%) We recommend object filling of 10% to 40%. (2) Filling pattern of the object and the first and last layer...
Page 123 (1) Loops are circles, that are drawn around the object when printing starts, stabilise the filament flow before the actual object is printed. Here, number, distance from the object, height and minimum length are specified. (2) "Brim" is a thin edge that is placed right around the object to increase the footprint and thus adhesion to the printing plate. Here, the width of the brim is specified. (1) Selection and adjustment of the supporting material that is needed when printing complex objects such as bridges or hollow spaces (poss. required for printing object with overhangs > 45°). The first printing attempts should be without a supporting brim since the result here is usually better again.
Page 124 You can set or adjust all speeds here. Chance the values only in small steps. Set the number of extruders here.
Page 125 The extrusion width for all the different print versions can be set here. The extrusion width is the width of the output plastic thread. E.g., this may be increased at the first layer, so that the bottom of the printed object becomes denser.
Page 126 Filament Settings (1) Filament diameter and filament diameter tolerances according to the manufacturer's specifications are set here. If no manufacturer's speci- fication is present, these values can also be measured with a calliper (measure 1 m of filament material in 10 different points and then set the average here). (2) Temperature setting for the extruder and heating bed (in the preassembled device or when using the optionally available heating plate kit) separated by first and all other layers. In some settings (e.g. PLA), the heating is deactivated by default. If this is to be used, the function needs to be activated first by set- ting a temperature. Observe the settings recommended by the filament manufacturer! Since the best values may fluctuate extremely depending on the filament manufacturer, perform your own tests based on the pre- settings to achieve the best printing quality. When performing the tests, proceed in 5 °C steps and compare the results during or after printing with other settings. The first layer should always be printed a little more hotly for better adhesion on the printing plate. (1) Here you can choose between automatic cooling and permanent operation of the fan at the extruder. (2) Setting of the fan speed.

(2) The end code will be performed at the end of the print and could contain, e.g. the run into a removal position for the printed object. Detailed information on the G-Codes can be found, e.g., in http://reprap.org/wiki/G-code.
Page 128 (1) Setting of the nozzle diameter (2) Settings for the filament withdrawal if the extruder moves to another position of the printed object during printing. If the filament was not withdrawn here, there would be drop or string formation that would negatively influence printing quality.
Page 129: I) Setting Up Another Slic3R Version
i) Setting up Another Slic3r Version This chapter describes how to set up another version of the slicer "Slic3r", e.g. if you want to use an older version as well or if a new version has been published since. • First download your desired version of Slic3r. You can find the corresponding download under the following address. http://slic3r.org/download Then click the button "Windows". If you want to download an older version, click the folder "old/"...
Page 130 • In the menu "Slicer", choose the desired Slicer that you want to integrate. In our example, this would be the standard selection "Slic3r". • In the field "Name", enter the desired name and confirm by clicking "Add Slicer". • Select the newly added Slic3r by clicking it (1). • Right-click "Browse" (2). • Navigate to the new Slic3r program directory in the window that opens and select the starting file, in our example "slic3r.exe", by double- clicking (3). • Select the "Slic3r" version (4) and confirm with "Apply" (5). Close the window with the X in the upper right corner (6).
Page 131 • In the tab "Slicer", select the newly added slicer in the drop down menu to slice an object. The settings "Print Setting", "Printer Settings" and "Extruder 1" are the same for both versions of the Slic3r. Of course, the configuration menu "Manager" also permits integrating another Slicer. The configuration here is similar, but is indi- vidually customised to each slicer, of course.
Page 132: Firmware Update
20. Firmware Update The firmware of the main PCB is updated frequently to optimise the properties of the 3D printer. The currently installed firmware version of your printer is briefly displayed in the upper display line after switching on the printer. New versions of the firmware are contained in the download package "BUNDEL_Vx_x_x_RENKFORCE_RF500". Update process The printer must be connected to the USB interface of the computer and must not be connected to any other software (for Repetier-Host, e.g. click "Separate"). Use only Arduino version 1.6.5. The links for download can be found below or in the download package. The first link leads to the main page. You can find the download there in "PREVIOUS RELEASES". The second link downloads the right version as a ZIP file and the third link as EXE file for installation. https://www.arduino.cc/en/Main/Software https://www.arduino.cc/download_handler.php?f=/arduino-1.6.5-r5-windows.zip https://www.arduino.cc/download_handler.php?f=/arduino-1.6.5-r5-windows.exe • Unpack the downloaded Arduino software. • Execute the file "arduino.exe" (folder "Arduino" and its version subfolders until you find the file "arduino.exe"). • In the menu "Tools" (1), select option "Board" (2) and set the type "Arduino/Genuino Mega or Mega 2560" (3).
Page 133 • In the menu "Tools" (1), select option "Processor" (2) and set the type "ATmega2560 (Mega 2560)" (3). • In the menu "Tools" (1), select the option "Port" (2) and set the correct port (3). The port number is system-dependent. You can find it in the device manager of the control panel, under connections (COM and LPT).
Page 134 • In the menu "File", choose the option "Open..." and select the file "Marlin.ino" from the download package. The file "Marlin.ino" can be found under the following directory path, depending on whether your printer has a heating bed installed or not: \Download Bundel Vx-x-x.zip\Firmware-Source\Firmware RF500\Marlin-with-bed\Marlin-x.x.x\Marlin\Marlin.ino \Download Bundel Vx-x-x.zip\Firmware-Source\Firmware RF500\Marlin-without-bed\Marlin-x.x.x\Marlin\Marlin.ino • A new window opens. • In the new window, click the button with the arrow to the right in order to transfer the new firmware to the 3D-printer. Once the update has started, the USB connection to the printer must not be interrupted. This may cause irreparable damage. • After a successful firmware update, the 3D-printer will start again and briefly display the new firmware version in the first display line after the start.
Page 135: Maintenance
21. Maintenance a) General Information Periodically verify the technical safety of the 3D printer, e.g. check for damage to the mains unit or of its mains line. If you have reason to believe that the device can no longer be operated safely, disconnect it immediately and make sure it is not operated unintentionally.
Page 136: C) Nozzle Change
Cleaning the printing plate Be careful in the preassembled device or when using the optional heating plate kit: Danger of burns. Let the heating plate cool off before cleaning. Clean and degrease the heating plate thoroughly with a soft rag after each print. If you are printing directly on the glass panel, use a little ac- etone for cleaning. If you are using the adhesive film use a mild detergent with alcohol. e) Nozzle Change Caution: Danger of burns. Do not directly touch the hot nozzle and the extruder. • To replace the extruder nozzle, the extruder must first be heated to a temperature suitable for the inserted filament material. • When the temperature is reached, remove the inserted filament material as described in chapter "16. c) Removing and Changing the Fila- ment".
Page 137 • Turn the extruder nozzle back into the heating block and tighten it carefully with a ring spanner, open-faced spanner or hexagon wrench (2). Never apply any strong forces for this. Secure the heating block again by twisting with an 11 mm open-faced spanner. • Then insert the filament again as described in "Inserting the Filament". • Switch off the extruder heating again and have the extruder cool off. View of the nozzles The following figures are to enable you to check your installed nozzle in case of a bad print pattern or if not enough filament is extruded. For example, it is possible that the tip of the nozzle is set incorrectly or comes into contact with the printing plate due to a printing error, and is scraped or damaged by this.
Page 138: Troubleshooting
22. Troubleshooting With this 3D printer, you have purchased a product that is built to the state of the art and operationally safe. Nevertheless, problems or errors may occur. Therefore, we would like to describe how to eliminate possible errors here: Always observe the safety information! The 3D printer does not work after connecting the voltage supply. The display and the LEDs on the main PCB remain dark: • Check the connection of the mains line at the mains unit, the mains unit and the connection of the mains unit to the printer.
Page 139 Printing stops during the process: • Check the settings of your computer. It must not switch to standby mode while printing (energy option settings) or simply shut down (instal- lation of software or software updates during printing). • The printing table and its guide must not be installed tensed. In this case, loosen all screws, align the parts and tighten the screws again. The printed object does not adhere to the printing plate: • Use the enclosed adhesive film (only in the maker construction kit) or the enclosed glue stick (only for the preassembled device). This in- creases adhesion of the printed object on the printing plate. You can also use cleaning tape or a slightly structured masking tape as well as Kapton masking tape or blue adhesive masking tape (Conrad order no. 1093104). • There are residues on the printing plate that prevent adhesion of the object. Rub the printing plate with a soft cloth that is soaked with a solvent (e.g. acetone). If you are using the adhesive film, use no aggressive cleaning agents for this. The printed object does not adhere to the printing plate (only in the preassembled device or when using the optionally available heating plate kit): • If you are using the heating plate, the temperature of the heating plate may be set incorrectly. Experiment with the temperature settings in steps of 5 °C for a prefect print result. • When printing problematic objects, it is beneficial to let the optional heating plate heat up for approx. 15 minutes before printing. • Check whether the heating (red foam material) adheres cleanly to the ceramics printing plate. It must not come loose (even partially). If this is the case, the temperature distribution of the heating plate is insufficient and the printed objects cannot adhere well. • The heating plate has not reached the set temperature yet. The printed object cannot be removed from the heating plate (only in the preassembled device or when using the optionally available heating plate kit): • If you are using the heating plate, wait until it has cooled off to below 40 °C. • Use a glass scraper or a knife to remove the object. Repairs other than those described above should only be carried out by an authorised specialist.
Page 140: Handling
23. Handling • Never connect the mains plug to a mains socket immediately after the device has been taken from a cold to a warm environment. The result- ing condensation may destroy the device. Allow the device to reach room temperature before connecting it. Wait until the condensation has evaporated. • Never pull the mains plug from the mains socket by the cable. Only pull it from the mains socket by the intended grip areas. • Disconnect the 3D printer from the mains voltage if you are not going to use it for an extended period of time. • Disconnect the mains plug from the mains socket during thunderstorms for reasons of safety. • The extruder can heat up strongly in operation. Do not touch this during or just after operation. Let it cool off again. 24. Disposal Electronic devices are recyclable and should not be disposed of in household waste! Dispose of the product according to the relevant statutory regulations at the end of its service life.
Page 141: Annex
26. Annex a) Fine Adjustment of the Filament Infeed This chapter describes how to adjust the filament feed precisely, e.g. to compensate for the tolerance of the feed knurl. Preparation • If it has not been done yet, install the software Repetier-Host incl. the drivers and connect the printer to the computer (see chapter "19. Software "Repetier-Host"”). • If necessary, set the COM port and connect the printer. The symbol at the upper left must be green and it must say "Separate" below. • When the printer is connected, switch to "Manual Control" in the software. The printer must only be controlled via the software throughout this process.
Page 142 • When the filament is marked, feed in precisely 50 mm. For this, move the mouse over the arrow at the lower left in the right control (see red arrow). When the mouse pointer is all the way at the bot- tom (see arrow tip of the red arrow) and the middle shows 50, click precisely once. • The filament motor now conveys precisely 50 mm filament and then stops again. • Now measure the remaining distance between the ball bearing holder and the mark just as you did when marking before.
Page 143 Calculation and correction of the feed The formula for calculation of the actually conveyed volume is as follows: Total length in mm - residual amount in mm = actually conveyed volume in mm 100 mm 53.37 mm = 46.63 mm The formula for calculating the new value "Steps per mm" is as follows: Conveyed volume in mm: Actually conveyed volume in mm * Current value Steps per mm = New value Steps per mm 50 mm : 46.63 mm * 127.00 = 136.18 • After you have calculated the value, open the EEPROM configura- tion. • In the menu bar, choose "Configuration" and the "Firmware EE- PROM Configuration".

b) Setting up the Printer Settings This chapter is only targeted at users who do not have the custom version of the software installed. If you have installed the custom version (can be recognised by the image of the RF1000 3D-printer when the programme starts), you may skip this chapter. It only serves information purposes then. Start the programme Repetier-Host and click on "Printer Settings" at the upper right in the window. (1) Name your printer RF500_3D in the following window in tab "Connection" or assign a name of your own. (2) Set the port and baud rate. The baud rate must be set to "115200". The port number (2) is system-dependent. Usually, the setting "Auto" should work with the current version of the software (as of 1.6.2). If this does not work properly for you, you can check the port in the device manager of the control panel, under connections...
